				<dd>对于 Non-CJK 文本允许在任意字符内发生换行。该值适合包含一些非亚洲文本的亚洲文本，比如使连续的英文字符断行。</dd>

				<dd>与<code class="g-value">break-all</code>相同，不同的地方在于它要求一个没有断行破发点的词必须保持为一个整体单位。这与<a href="word-wrap.htm" class="g-property">word-wrap</a>的<code class="g-value">break-word</code>值效果相同</dd>

				<li>
					<p>同为强制打断单词的<code class="g-value">break-all</code>与<code class="g-value">break-word</code>的两个值，需要了解她们间的主要区别（下述2个示例需要在webkit/blink浏览器下查看）：</p>

						<p class="gquote-info">break-word同样也会在文本内容遇见边界时，强制将文本打断换行，不同的在于它会考虑单词是否完整，如果当前行无法放下需要被打断的单词，为了保持完整性，会将整个单词放到下一行进行展示</p>
